The web plate of the post sleeve as position-fixing members. More particularly, the well as the jib portion of the bracket sleeve may invention relates to a bracket arrangement of be shaped in any suitable manner. The post 10 this kind comprising a bracket supporting post sleeve may, for example, constitute part of a free 10 or upright. standing post or be provided with fixing wings for The arrangement according to the invention securing the sleeve to a wall or the like by means which is convenient in operation and can be pmof screws. The bracket sleeve may be connected duced at a small cost on account of its simple conin an arbitrary manner with an arm or hook or struction, is characterized substantially therein for example with a shelf, a platform or the like 15 that the bracket and the post are provided with made in any suitable manner. sleeves adapted for displacement within each In order to prevent lateral turning of the other and composed of plates rolled together subbracket sleeve in cases when only a Single P stantially in the shape of spirals. sleeve is used it is preferable to shape the in- The invention will be more particularly devolute or spiral of both the post sleeve and the 20 scribed with reference to the accompanying drawbracket sleeve with plane S Walls which u de ing wherein preferred embodiments are illusach Other mutually as shown in Figure 4.

In the embodiment illustrated in Figures 1 to 3, The arrangement acc o he invention the sleeve for the braeket-earrying post or upis of particular interest f0! scaffolds 0f the kind right is made of a plate I, Figure 1, which plate where it is desired to be able conveniently to at one longitudinal edge 4 thereof is formed with Shift a Work-platform the like to q ed 35 equally spaced recesses or notches 3. The bracket elevation While W is going sleeve required for connecting the bracket to the A plurality 0f modified embodiments according post is made of a rectangular plate 2, said plate to the invention are possible. Thus, the sleeves being provided at its upper and lower edges with y be made with a D d P fi tubular 40 two teeth 5 and 6 which project in opposite diin which latter case the sleeve is provided with 40 rections in order to adapt the sleeve both for a. a lon i n l sl The bracket sleeve need not right hand and a left hand post. In Figure 2 is necessarily be provided with projecting teeth but illustrated the engagement between the bracket the end edges of the Sleev m y ve he ame plate 2 and the post plate I, the bracket plate bepurpose as the teeth. The term involute as ing shown in a position corresponding to a loaded used in the claims is employed in its generic sense 45 bracket. to mean spirals or the like whether the sides At its notched edge, the plate piece I is bent are curves, straight lines with right angle bends or rolled together for example to form a spiral or similar to rectangles, or straight lines with acute involute as illustrated in Figure 3, the notched angles to give the general appearance of a triedge 4 being bent a full turn. The plate piece 2 angle. When the sleeve is made in the shape of is also rolled together to form a spiral or involute an involute with curved edges the locking means and in such-a manner, that the edge provided may be released by turning the bracket member with the teeth 5 and 6 will lie in the same plane or by relieving the weight on the bracket and as the unbent portion of said piece of plate. The drawing it as far as permitted directly away from sleeve-shaped portions of the plates I and 2 are the base which is the method of releasing when 55 a generally rectangular or triangular sleeve is employed.

I claim:-

1. An adjustable support for shelves, supporting arms and the like comprising a base member provided with a sleeve involute in cross section, a bracket member also provided with a sleeve involute in cross-section telescoping with the sleeve of said base member and means on each member mutually engageable at the centers of the sleeves. a

2. An adjustable support for shelves, supporting arms and the like comprising a base member provided with a sleeve involute in cross section; and with notches at the inner edge, a bracket member also provided with a sleeve having teeth at the inner edge, involute in vcross-i-section tele-- scoping with the sleeve of said base member, said teeth and notches cooperating to hold the bracket member in any desired position.

3; An adjustable support forvshelves, supporting arms and the-like comprising a base member provided with a sleeve which is a one turn involute in cross-section, a bracket member also provided with a sleeve which is a one turn in.- volute in cross-section telescoping with the sleeve of said base member and mutual engaging means on each member operative when the base member and the bracket member are in planes substantially at right angles.

4. An adjustable support for shelves, supporting arms and the like comprising a base member provided with a sleeve which is a one turn involutein cross-section, a bracket member also provided with a sleeve which is a one turn involut'e'in cross-section telescoping with the sleeve of said base member and mutual engaging means on each member operative when the base member and the bracket member are in planes substantially at right angles and slidable when the bracket member and the base member are in planes approaching parallelism.

5. An adjustable support for shelves, supporting armsand the like comprising a base member spirally bent along one edge until that edge extends in the same direction as originally, a bracketmember telescoped with the base member by i a. portion spirally bent along one edge until that edge extends in the same direction as originally,

and cooperating means to hold the bracket member and base member in fixed relative positions.
